First the ASUS Padfone, then the CMIT TransPhone, and now a third phone-docking tablet but with a little extra spice. Our latest contender comes from a Taiwan-based startup dubbed ICE Computer, who has just announced its partnership with ECS over its Trinity concept, a mobile display that lets you dock either a PC module or a smartphone (not necessarily an iPhone, let alone an iPhone 5 as reported by some sites; the dummy's just for show and convenience). From our quick chat with ICE product manager Jaryson Wu, we learned that the company's been working on this project for quite some time, though ike ASUS and CMIT, ICE also lacked a working prototype to show us.

So the idea is simple: slide in a PC module or phone of your choice, and you have yourself a fully functioning touchscreen tablet that has an upgradable core -- that's one tick for environmental friendliness, and another tick for potentially more powerful upgrades. But that's not it, as ICE may also throw in USB 3.0 ports, additional internal storage, and even a fan inside the Trinity tablet, but that will depend on the clients' needs. Jaryson indicated that there are no plans to launch products under the startup's own brand, nor is it going to develop its own phone to go with the add-on any time soon -- we'll just have to wait and see what it'll deliver in the first quarter of 2012. Video interview after the break.
